Variable-depth grooves are deepest in the center and get gradually shallower toward the perimeter to equalize ball speeds across the face for unmatched distance control. PING studies show an increase in ball-speed consistency of nearly 50% compared to a non-grooved face when measured at nine points across the face. An elastomer back-cavity insert repositions mass from the face to enhance sound and feel while increasing MOI for maximizing forgiveness.

Karsten TR putters fit all three stroke types: straight, slight arc, and strong arc, which are easily identified by color-coded shaft labels. Results from hundreds of player and robot tests at PING show that you'll putt more consistently when your putter balance matches your stroke type. The distinctive copper PVD finish is non-glare to eliminate distractions.
